Description

Technical Field

[0001] The present invention relates to the technical field of stepper motors, and more particularly to a high-voltage-resistant wet stepper motor. Background Art

[0002] A stepper motor is a motor that converts electrical pulse signals into angular displacement or linear displacement. Under the action of each pulse signal, the rotor of the motor will rotate a fixed angle, called the step angle. The characteristics of this motor are simple control, accurate positioning, and precise position control without a feedback system. Due to its simple structure, low cost and easy control, stepper motors are widely used in various automation control systems, such as printers, plotters, CNC machine tools, robots, etc.

[0003] According to the patent document: CN116800045A, a high-pressure resistant wet stepper motor is disclosed, including a stator, a rotor and an end cover assembly. The rotor is sleeved in the stator, and the axial length of the stator is greater than the length of the rotor. The stator includes a grid-shaped magnetic isolation ring, which is sleeved in the stator core and has an interference fit with the inner circle of the stator core to ensure the high-pressure resistance of the grid-shaped magnetic isolation ring. While the grid-shaped magnetic isolation ring provides a magnetic conductive path, it forms a high-pressure resistant sealed cavity for accommodating the rotor together with the two end cover assemblies. The rotor is connected to an external hydraulic element, and the hydraulic element is driven to rotate to the expected position by rotating the rotor at a preset angle. The high-pressure resistant wet stepper motor of the present invention eliminates the seal at the rotating shaft required for driving and controlling the hydraulic element of an ordinary dry motor, avoiding the problem of high-pressure dynamic sealing of an ordinary dry motor. At the same time, the stepper motor that controls the hydraulic element is designed as a wet structure, which can effectively improve the heat dissipation of the stepper motor and reduce the temperature rise problem caused by the large heat generation of the stepper motor.

[0004] Generally, high-pressure resistant wet stepper motors achieve heat dissipation by optimizing the cooling system inside the motor during operation. The system uses the coolant circulation inside the motor to take away the heat generated by the motor during operation, thereby reducing the temperature of the motor. In addition, a certain gap is maintained between the stator and rotor of the motor to reduce friction and heat generation. However, the casing of the stepper motor is usually connected by bolts. When the stepper motor performs some high-power work, these connection points may become loose due to thermal expansion, affecting the stability and sealing performance of the motor.

[0041] Working principle of the present invention: When the stepper motor is assembled as a whole, the bottom mounting plate 3 and the top mounting plate 2 are placed on both sides of the motor housing 1. At this time, the top mounting plate body 21 presses the slide bar 5110 downward through the columnar pressure rod 22. When the slide bar 5110 is pressed downward, the second rotating rod 516 fixed to the outer wall of the slide bar 5110 is driven to rotate and pull the rotating rod 515 to rotate, and then the rotating rod 515 drives the hinged rod 514 to rotate with the rotating shaft 513 as the axis. 513 rotates, thereby driving the bottom rotating rod 515 and the second rotating rod 516 to rotate and pull the bottom tube 517 and the top tube 518 to move upward, and the sliding rod 5110 slides on the inner walls of the bottom tube 517 and the top tube 518, and the bottom tube 517 and the top tube 518 pull the bottom mounting plate 3 upward to be close to the bottom of the motor housing 1. At the same time, when the columnar pressure rod 22 presses the sliding rod 5110 downward, the sliding rod 5110 drives the sliding rod fixing block 5249 and the pulling blocks 5248 on both sides to move downward. The two pull blocks 5248 pull the inner rotating rod connecting plates 5244 on both sides to move inward, thereby making the two outer clamping plates 5242 and the clamping plate body 5241 on the inner side move inward, and the outer wall of the columnar pressure rod 22 is clamped by the two clamping plate bodies 5241, thereby reinforcing the connection between the columnar pressure rod 22 at the bottom of the top mounting plate body 21 and the reinforcing mechanism 5.

It can not only withstand high-pressure environments, but also has high accuracy and stability during operation, meeting the needs of high-precision control and high-pressure resistance in industrial applications.

[0042] When the pulse male connector is inserted into the female connector 32, the staff operates by rotating the screw rod 411, and the rotation of the screw rod 411 is transmitted to the transmission cross bar 410, thereby driving the lifting rods 49 on both sides to lift the overall control slider 44, so that it slides toward the top in the side slide groove plate 42. Along with the movement of the overall control slider 44, the two sets of sliders 43 also slide toward the top along the side slide groove plate 42, and then pull the V-shaped rotating rod 46 through the U-shaped hinge plate 45 to realize the rotation with the V-shaped rotating rod 46 as the axis. The rotation of the V-shaped rotating rod 46 causes the limit frames 48 on both sides to move inward. , to clamp the outer wall connected between the female connector 32 and the male pulse head to complete the sealing and positioning. This mechanism ensures the stability and sealing of the connection under high pressure environment, and prevents the risk of external impurities in some environments entering the entire interior through the female connector 32 and affecting the normal operation of the equipment. In addition, through the coordinated work of the screw rod 411 and the transmission cross bar 410, the operation process is simple and easy to fine-tune, which improves the overall accuracy and durability, and also simplifies maintenance work. The entire design takes into account the actual application needs under high pressure environment to ensure the reliability and efficiency of operation.
